Crowley also took a shot at Ocasio-Cortez and said he was not willing "to air grievances on Twitter."

"Alexandria, the race is over and Democrats need to come together," Crowley tweeted. "I've made my support for you clear and the fact that I'm not running. We've scheduled phone calls and your team has not followed through. I'd like to connect but I'm not willing to air grievances on Twitter."
